' vertical position, and the top 2 of said box 2O is connected inlile,mannerat' its other end at joint 21 with bar-22, which is ofgreater length and'which in'turn at its other end is pivotally connectedwith the Aupper end of upright 23. Between its ends bar 22 is bent in'sucha manner that that vsectionlies close tothe vertical ortion ofrailX. Bars 20 and 22 are of suclh a length 'that when upright 19 standsin a vertical dpositionthe oblique angle formed by 20 an 22 at joint 21projects above the top of rail X, and when upright 19 is swung down indirection of train movement said bars 20 and 22 will lie at joint 21 ona level with the top of rail X. From the inside of the upper end ofupright .19 rojects an eye-29 to which is attached 'a ro 18 attached atits other end to rod 15', which, as;- has been described, isconnected'w-ith plate 1 0 in sucha manner that when upright 1 9isverticalsaid plate 10 will have swung, in a j direction opposite tothat of train movement,

onv its 'vot 11 to a position practically paral-` lel wit the bottom ofbox 1. To vthe saidother enduof 18 is 'also attached rod 24,.'at-ltached to'the other end of which is chain 25 leading around wheel 26yand u through signal tower B to the inner end o danger signal arm 27 insuch a manner that when upright' 19 is vertical, said arm 27 will bein averticali) position, or not in use. Thus it will be seen-l that whenupright 19 is swung: in direction of train movement on its pivot by thedepress-` ing of bars 20 and 22, at joint 21, the plate 1,0

(Fig. 4) in box 1 will assume a verticalfposition thereby raising oneend of cover 2 and also danger signal arm 27, Fig. 1, will assume ahorizontal position and show a danger s i nal to approaching trains 1nconnection w1t lsafety signal arm 28, which is ordinarily displa edalone. To eye 29.is also attached one en of'a rod 17 which extends in adirection oppositeto that of train movement to the beginning of thepreceding block where its',v othercn is attached -to a chain 13 and its?connections (described in connection with. Fig. 4) in such a mannerlthat when upright4 19, lin any block, is swungin direction of 'trainmovement on its pivot, as has beendey scribed, the late 3 (Fi 4) inthepreeeding block track ox A wil be pulledfrom the lowered, while bymeans of rod 1'5 connected to plate 3 in said box the upright 19 of thesaid preceding" block device will be swung to a vertical-position,thereby raising the joint 21 of ,rods 20 and 22 above the level oftherail X and through rod 1S etc. dro ping lb ook danger signal arm 27.ofsaid preceding to a vertical position out of use. j

The construction of Fig. l'lias already been described inthatorI Fig. 2.

In Fig. 5 is shown a sectional end view taken on line 5-5 of Fig. 4 andshowing plate 10, rollrfl, rod 12, etc.

Fig. 6 represents the train section'C, or

that portion of our improved sto", device which is attached to the trainitse f, being preferably fastened to the locomotive at the "rear righthand side o1" the cow-,catcher and thus adapted to travel oversuccessive track boxes A. This section C comprises a plate 30, attachedto the en ine, secured to the lower end of which is cy inder 31, and tothe upper end cylinder 32 spaced apart'from 31 near the center of plate30. Cylinder 31 is pierced by a bore permitting of movement therein ofrod 3 3, w lich rod terminates at its lower'end in a foot 35., A collar34 near the upper end of rod 33l permits' the rod to project far enoughbelow the cylinder 31 to allow the foot 35 to come'in contact with andbe fpushed up by the cover 2 of a track box A when any part ol saidcover is raised (best shown in Fig. 1) while another collar 34 near thevlower end vvof rod 33 prevents said rod from being pushed up through thecylinder 31'more than a required distance. Cylinder 1,32 is also iercedby a central 'bore terminating near t 1e tolp in a cylindrical chamber46 with a funne shaped bottom. Rod 36 moves in the bore in cylinder32,.extending 'below the same until in close proxmity to the upper endof rod 33 when said rod 1s in its lowest position and terminatingl atits upper end in a head 37 itting in the funnel-'shaped 4bottom ofchamber 46. From the center of this head '37 and integral therewithprojects a vertical rod 38' which is encircled by a spiral spring 39;spring 39a rests on the head 37net. the bottom and'- at the top bearsagainst a tfop member 47 which closes the chamber 46. Thus the spring 39normally tends to keep the head 3-7 in its seat While a recess 40 insaidtop 4T over rod-38permits said rod to move upwardwhen theV head 37 isforced out .f-.fits Seatby pressure on the lower end of the su()l rod"36'.' VNear the bottom ofthe cylinder 3 2 a'pin .42 passesin andpressedy against the 'rod 3 6`by a spiral sprang 43; in rod 36 justbelow the point wherethe .ino/12 abuts saidv rod, whennlits normal orowered position,

is Vanannular recess 41 into which the said .pin 42 is forced by thesprin 43 When the rod 36 is pushed upwards, and t us said rod can.
